“Most of the cases reported in Italy were identified in the last 14 days in unvaccinated subjects” and “it is estimated a strong effect of reducing the risk of Sars-CoV-2 infection in fully vaccinated people compared to unvaccinated people (88 % for diagnosis, 95% for hospitalization, 97% for intensive care admissions and 96% for deaths) ». These are the data contained in the extended document of the weekly monitoring of the Supreme Institute of Health (Iss). In particular in the last 30 days, 33% of Sars-CoV-2 diagnoses, 46% of hospitalizations, 71% of ICU admissions and 69% of deaths occurred among those who did not receive any dose of vaccine.
Covid and green pass, Brusaferro: «The vaccine is the best method to convince no-vaxes. Also effective on the Delta variant “
And on the effectiveness of vaccinations: from 4 April (approximately the date on which vaccination was extended to the general population) to 18 July 2021, the overall efficacy of vaccination, adjusted for age – reads the report – is greater than 70% in preventing infection in vaccinated with incomplete course (70.2%) and above 88% for vaccinated with full course (88.2%). The effectiveness in preventing hospitalization rises to 81% with an incomplete cycle and 95% with a full cycle. The effectiveness in preventing ICU admissions is 89% with an incomplete cycle and 97% with a full cycle. Finally, the effectiveness in preventing death is 80% with an incomplete cycle and 96% with a full cycle. “These estimates – specifies the ISS – are not adjusted for various factors that could affect the risk of infection / hospitalization / death and the probability of being vaccinated (for example, risk category, comorbidities, etc.)”.
